What are phones for? Why do children need a mobile phone. What does the word Libra mean?

Electronics manufacturer cooler master It has whole line hardware products such as keyboards, power supplies, headsets, computer (PC) cases, mice and, of course, coolers. Each of its products has been custom designed based on community feedback. Including keyboards. Cooler Master even had a Kickstarter project, an analog keyboard with pressure-sensitive keys called the ContolPad. With that said, let's take a closer look at what can do new keyboard Cooler Master SK621 is special for the user.

Keyboard news: Cooler Master SK621 review - a mechanical wireless keyboard with a separate wired option.

The first thing that is noticeable during the review is the ability to conveniently pair the wireless keyboard with three different devices. Connecting a device is as simple as holding the function button and Z, X or C. This feature makes it very easy to switch from using your phone to using your computer. Turning on the Cooler Master SK621 keyboard is also easy. Or connect via USB cable Type-C, or on the left side, activate a very simple switch to wireless mode.

Specifications of Cooler Master SK621 Wireless Keyboard:

Can display a wide variety of colors (shades) to any key, adjust lighting modes, or set up macros with software coolermaster.

When using the SK621 for the first time, it is recommended to connect to the computer via USB Type-C and install the Master Portal Cooler. This will allow you to control various lighting effects and wireless keyboard settings. It is possible to create preset profiles, which makes it easy to switch between profiles when using elements. You can also adjust the lighting effects with the controls, but the portal mentioned above is more user friendly. The wireless keyboard setup is very easy to use and has many combinations. There are options - adjusting the speed, direction and brightness of the keyboard backlight effects.

Macros can also be programmed. It's also worth adding that all functions such as RGB lighting, macros and controls are available when using the SK621 via a Bluetooth connection. Time battery life the wireless keyboard is also impressive. It may take a couple of full working days before the indicator turns red, indicating that the battery is low. Charging the SK621 wireless keyboard is also easy. Just connect your keyboard via USB Type-C. The keyboard can still be used as a wired keyboard as long as the cable charges the keyboard battery.

The body of the keyboard is crafted from brushed aluminum, making it lightweight, durable and looking great. There is also a nice smooth accent on the edge of the aluminum which adds a touch of elegance. The keys are made of plastic and don't have much texture.

The low-profile Cherry MX keys are quiet enough for office use. The key switches are incredibly responsive, and using the Cooler Master SK621 wireless keyboard takes some practice. This is because the keys register a press to the nearest millimeter or less.

The SK621 keyboard is designed compact, it is quite portable. A nice addition is a velvet bag. It's definitely made for gaming thanks to the Cherry MX keys, but it's easy to use for work.

The Cooler Master SK621 does everything it's meant to do. However, the keys are great for gaming, but too sensitive for typing. Plastic keys are also prone to oil stains on the fingers, so eating while playing can be tricky. Maybe if the keys had some sort of oil resistant coating or more texture, the oil prints wouldn't be as pronounced.

The ETH Zurich (ETH Zurich) has unveiled the details of "Concrete Choreography", an installation that has recently opened in Riom, Switzerland. The groundbreaking installation features the first robot-built 3D printed concrete stage, consisting of formworkless columns 3D printed to full height in 2.5 hours. This process is expected to significantly increase the efficiency of concrete structures while achieving the fabrication of complex material components and construction robots.

3D printing news: ETH Zurich creates concrete columns with a special concrete 3D printer.

In the Swiss Riom, at the Origen festival, nine columns 2.7 meters high are installed. Each column is 3D printed with concrete. The new columns were individually designed using special software and manufactured using a new automated concrete 3D printing process developed by the ETH Zurich team with support from NCCR DFAB.

3D printing from concrete

Masters in Digital Manufacturing and Architecture students explore the unique possibilities of the multi-layer extrusion printing method, demonstrating the potential computer design and digital fabrication for the future of concrete construction. Perhaps the construction industry this process will become more environmentally friendly in the future if they develop new eco-concrete for 3D printing.

Video review of 3D concrete printing: Concrete choreography.

Here's how easy and fast concrete 3D printing works.

3D printing of houses, concrete buildings is a perspective for construction.

Hollow concrete structures are printed for the strategic use of materials, providing a more sustainable approach to specific architecture. In addition, the calculated material structure and surface textures are an example of the versatility and significant aesthetic potential of concrete 3D printing when used in large-scale structures.

The new review will be about printing on a 3D printer with metal.

It is worth noting that there is a technology that would carry out 3D metal printing. It's the same promising direction for construction, but other materials are used for this (for example, powder), programs and other types of printers (which we will talk about soon).

What color is your mobile phone? Is it black, red, white, gold or blue? Most likely, rear part your phone has some kind of single color variant that you will find in the beginner coloring set. It's taken too long for most phone manufacturers to realize that phone colors really matter to customers, and it's only recently that they've started giving mobile phones not only a rarely used color, but fancy hues like coral red or canary.

Honor News: With the new 3D holographic color phones from Honor, it's possible to add some new color to life.

Unsurprisingly, most people don't mind hiding the backs of their phones behind opaque plastic cases. In cases, the user can choose the appropriate color of the phone case to give the mobile a bit of personality. But the new Chinese Honor 20 Pro and Honor 20 series phones are the world's first smartphones with a 3D dynamic holographic design, and their reflective exterior could become the new industry standard.

"Always better" is the motto of the company. Perhaps this motto indicates that she refuses to follow the industry standard, simply experimenting with layers of paint when creating each new phone model.

Color 3D holography for phone case.

In order to achieve a shimmering optical illusion for the body of the phone, manufacturer Honor has designed its Honor 20 with a depth layer containing millions of shimmering microscopic prisms, and on top of this is placed a so-called 3D curved glass layer. The combination of these technologies makes the light "play and dance" on the back of the phone when the user turns it in different directions.

Two colors for the Honor 20 phone can be found under these dynamic layers, they are Midnight Black and Sapphire Blue. Unlike the newfangled phrases for some phone colors, the mobile Honor has color gradients for phones that really evoke the effect of a shimmering night sky or a shimmering gem.

Although the color options of the cases sound exciting, with the Chinese phone Honor 20 Pro, you can go even further. This upgraded model contains the proprietary "3D Triple Mesh" containing three layers. Instead of just painting the back of the phone itself, this time with a body color layer, sandwiched between the outer 3D layer and the inner depth layer. According to the handset manufacturer, this makes the color shift effects much more dynamic.

The Honor 20 Pro mobile phone is actively sold in two colors such as phantom black (Phantom Black) and phantom blue (Phantom Blue). Although the names of these phone colors are not so metaphorical, you should not think that their rear panels are less dynamic.

Honor's obsession with choice correct colors may sound overly dramatic, but in the UK, for example, a survey of hundreds of Britons found that forty-nine percent of them consider color when choosing a phone to buy.

What is the sale of a phone with a changing color scheme for?

The choice of a mobile phone, as Honor designer Jun-Soo Kim put it, is "Prolonging a person's life." In essence, Honor is stating that customer identities cannot be captured by one unchanging color.

The history of the creation of color phones Honor.

The Honor 20 shows a natural evolution of the company's experimentation with dynamic color in phone design. With the Honor 8, the trend of a 2.5D layered back wall, which creates a 3D lattice effect, began. The Honor 9 version then evolved into a phone with 3D curved glass, echoes of which can be found on the Honor 20. Well, last year the Honor 10 featured an Aurora back glass that reflected colors from all sides.

What is it, the screen in the Honor phone?

Honor's design innovations are not limited to the color of the phone's body. It is worth paying attention to the placement of the Honor 20's camera. Instead of cropping the screen to make room for the "selfie" camera. The phone manufacturer has cut a 4.5mm hole in the top left corner of the screen, leaving more screen real estate for the user's needs.

AI camera or AI camera on your phone.

On the phone's description, it's worth noting that on the back of the handset, the Honor 20's AI camera has four lenses and is positioned to leave more space for the battery with more storage. But most importantly, the result is a 48-megapixel camera that uses the Kirin 980 AI microchip to take DSLR-level stills and enhance photos.

Honor phone color summary.

In summary, phone descriptions, technical compatibility, and cutting-edge hardware innovations are what usually draw attention to Chinese phones Honour. But, in this case, the technology is almost dwarfed by the uniquely colored case design, which may make some users reluctant to go back to plain 2D phone case colors in the future.

Rumors continue to arise about the release of the mobile google phone Pixel 4. A new set of information or predictions comes from an image leaked online (3D rendering of color cases) that is believed to be related to Google Pixel 4. It is not uncommon for users who follow the topic of new products to miss such images from attention. In the meantime, for some analysts, the new picture helps make a few guesses about more than just the color of the phone.

A new, unofficial image of the Google Pixel 4 gives rise to rumors about the color options of the mobile phone's body.

While another image of the phone's body itself doesn't seem to show any more than what's been discussed online before, the model seen in the background of the photo is surprising because of the color. That mobile phone has a shade of magenta that the Pixel model didn't have before.

Elsewhere, there have been other leaks of the same Google Pixel 4 with "three phones" (variants) stacked in a row. There are white and black colors plus a third has a bluish tint that some call mint green. Would you like to buy a blue phone? Probably the name of the colors of the phone will still be updated.

Whatever the phone's color leak may be true or false, it's safe to assume that this year's new Google Pixel 4 will definitely feature an additional color. More interestingly, in the image, the physical buttons on the sides of the phones contrast with the body color. You can see white, blue and yellow buttons that give the phone a fun look.

For some strange reason, all the images and leaks seen so far only showed the back panel. Google smartphone Pixel 4. As reported in various sources, supposedly Google shared a rendering of the phone, and there was also the part where the square camera bump was featured. The double camera block was visible.

The leaked photos in question, including the image along with the cases, show the rear panel in different colors and the camera module. What do you think is the best phone color?

Pro specifications Google Pixel 4:

Obviously, the idea of ​​a fingerprint scanner does not leave fans alone. Some wish the phone had either face ID to unlock the phone, or an in-display fingerprint scanner, or both.

Some other aspects and specifications, such as the dimensions of the phones and the overall thickness of 8.2 millimeters higher than the 7.9 mm seen in the Google Pixel 3 and Pixel 3 XL, can be taken as close to reality.

There is speculation that Google's Pixel 4 and Pixel 4 XL versions of the phone may be more like a variant of " Apple iPhone 11", which is scheduled to release in a couple of months, in the fall. When, exactly? Tech company Google has yet to announce an official release date for the Pixel 4, but various sources are hinting at a release of the new phone at the end of October.

Soon, we will talk about this in more detail, so stay tuned for news about new smartphones from Google.

The robot set the world record for solving the Rubik's Cube. This robot was developed by MIT students Jared Di Carlo and Ben Katz in a student lab. In comparison, the fastest human record is held by Australian Felix Zemdegs, who in 2018 solved the Rubik's Cube in just 4.22 seconds. By the way, the original size Rubik's Cube has 43 quintillion possible combinations for one solution. Watch the video with the record holder robot below.

Robotics News: Nimble MIT Robot solves Rubik's Cube in a world record time of 0.38 seconds.

There is a special place in the hearts of many people for the Rubik's Cube. This is a good workout for the intellect. Many have loved or still love to play with this ingenious toy, and over the years there have been many contests, challenges and variations on the Rubik's Cube solution.

The popularity of the Rubik's Cube can be attributed to the simplicity of its design, combined with the mind-boggling difficulty of the puzzle.

New record for solving Rubik's Cube 3x3x3.

Engineers and hobbyists have been using robots to solve Rubik's Cubes for years. 10 seconds used to be considered a quick build, but by today's digital age standards, that time is a smile.

A new record was only a matter of time before engineers and roboticists began to tackle the challenge of creating a new robot. Back in 2016, a robot set a new record for solving a Rubik's Cube in 0.637 seconds. But for some enthusiasts, that time wasn't fast enough.

More recently, two MIT students, Jared Di Carlo (third-year electrical and computer science student) and Ben Katz (mechanical engineering graduate student), thought they could build a faster robot that could solve a 3D combination puzzle.

They looked at videos of previous robots and noticed that the robots' engines weren't the fastest they could use to solve the problem. So we thought we could do better with better engines and controls.

How does a robot collect a Rubik's Cube

The students installed an electronically controlled motor that powers each face of the Rubik's Cube. Using a pair of webcams aimed at the cube, special software determines the initial state of each side of the cube (what colors are on which side of the cube at a given time). Then, based on the information received, using the already existing software for solving the Rubik's Cube, the robot solves puzzles using the algorithm.

What is the result of the work? Their robot solved the Rubik's Cube in 0.38 seconds! It's safe to say that no human is physically capable of breaking this speed record. One more achievement could be added to the list of robots surpassing humans.

There is a man who holds the fastest world record for manual assembly, his name is Felix Zemdegs. He was able to complete the Rubik's Cube in 4.22 seconds. The skills and talents that robots are replacing are vast and varied, to say the least. Not to mention that robots can still surprise. Below is a video demonstration of the robot.

Video review of the assembly of the Rubik's Cube in 0.38 seconds:

So, hardware hackers, Ben Katz and Jared Di Carlo, broke the previous record for robotically collecting the Rubik's Cube. Their robot solved the puzzle 40 percent faster than the previous record.

Details about the record-breaking robot

The robotic fixture is assembled from the Kollmorgen ServoDisc U9 series motors, PlayStation Eye cameras (for scanning the cube) and, of course, a Rubik's Cube was needed. According to the creators of the robot, - "The entire software process takes about 45 milliseconds. Most of the time is spent waiting for the webcam driver and determining the colors on the sides of the Rubik's Cube."

Artificial Intelligence Research Group Facebook Inc. introduced new platform for robotics called PyRobot. This platform (framework) was developed in collaboration with researchers from Carnegie Mellon University. PyRobot is designed to help AI researchers and students integrate deep learning models built using the PyTorch platform (a machine learning library for the Python programming language) with the robots they create. The basic idea is that they can build their robots more easily using artificial intelligence skills such as natural language processing.

News from the world of robots with AI (AI): Facebook introduces the PyRobot robotics platform, an open source framework for controlling robots.

Facebook said it wants to promote long-term robotics research to help develop embedded AI systems that can learn more effectively by interacting with the physical world.

Previously, to stimulate the production of artificial intelligence models, the company introduced the PyTorch Hub.

What is PyRobot today

PyRobot is a lightweight, high-level interface that provides independent hardware APIs for robotic manipulation and navigation. The PyRobot repository also contains a low-level stack for LoCoBot, a low-cost mobile manipulator hardware platform (robot assembly toolkit). Now artificial intelligence and machine learning is becoming more accessible for newcomers to robotics.

Research Director Abinav Gupta and Saurabh Gupta, as a Facebook Research Fellow, explained in their blog that: PyRobot is a lightweight, high-level interface on top of operating system robot. It provides a consistent set of middle-level device-independent APIs (Application Programming Interfaces) for controlling various robots. PyRobot abstracts away details about controllers low level and inter-process communication, so machine learning and others can simply focus on building high-level robotics applications with AI (artificial intelligence).

The Facebook source also says that PyRobot has dozens of potential applications, such as helping researchers share data and set benchmarks and build on each other's work. The company has solicited input from the broader AI research community on how to democratize robotics with LoCoBot and PyRobot, which is a hardware specification and toolkit for building low-cost robots.

PyRobot works by using an API to abstract the functions that robots should use. Perform tasks such as kinematics, trajectory planning, position, speed, and torque control for joints, and visual simultaneous localization and mapping. PyRobot comes with a number of pre-trained deep learning models that allow robots to navigate, grab objects, and so on.

This means developers can program their robots with just a few lines of Python code, according to Facebook.

More researchers from Facebook say that: The cost of hardware and the complexity of specialized software limit the scope of research in the field of robotics. With lower barriers to entry, researchers can, for example, create multiple robots that collect data and learn in parallel. Providing common platform for various equipment. PyRobot will lead to the development of tests in robotics, similar to other areas in AI, and will quantify the pace of progress in robotics with artificial intelligence.

Like Amazon's RoboMaker tool, PyRobot runs as an interface on top of the Robot Operating System (ROS), extending the infrastructure. Tech company Microsoft released a limited preview robotics toolkit in May, and last year integrated the ROS platform into Windows 10.

Renowned analyst and forecaster for Apple smartphones, Ming-Chi Kuo, by far, may be the most reliable source of leaks and information about Apple products. And today he released a new research report obtained by Mac Rumors where he mentions the future of the iPhone and when can we expect Apple to finally switch to 5G smartphones ( mobile communications fifth generation).

Rumors and Technology News: Analyst Ming-Chi Kuo Predicts Apple to Release 5G iPhone in 2020

When Apple was still planning to use Intel modems in its iPhones, there were rumors that the "iPhone 2020" phone model would be the first to receive 5G connectivity. However, the Apple company has since switched from its modem supplier to Qualcomm. For which they had to settle a long patent dispute with an American chip manufacturer, pay at least $4.5 billion and not use Intel modems. Perhaps Intel even closed its 5G development plans after this news.

According to analyst Kuo Ming-Chi's note, the development new version mobile iPhone 5G is on track. Allegedly, we will see Apple announce the iPhone 5G in 2020. Also in Kuo's note, it is mentioned that as a 5.4-inch iPhone model, and the 6.7-inch iPhone model will have a 5G modem. There is a hint of some iPhone update XS and iPhone XS Max smartphones.

Ming-Chi Kuo also said that all three iPhone models in 2020 will come in multiple colors and feature an OLED screen, as opposed to the LCD screen in the current iPhone XR. However, this year we will probably still get an update to the LCD iPhone XR, so if the OLED screen in a mobile phone is too much for you, maybe wait a year.

5G iPhone competitors:

Currently our best competitors on Android system are the following 5G phones:

1) Xiaomi Mi Mix 3 5G (128 GB storage, 6 GB RAM and battery with fast charging);

2) OPPO Reno 5G (innovative design, affordable price, powerful camera);

3) LG V50 ThinQ (screen 1440 by 3120 pixels, memory expansion up to 1 TB, battery 4000 mAh);

4) OnePlus 7 Pro 5G (frameless AMOLED screen without notches and holes);

5) ZTE Axon 10 Pro 5G (48 megapixel camera, Snapdragon 855 chip).

Global sales of 5G phones.

Global shipments of mobile phones with 5G technology (this is a fast fifth-generation mobile connection) to stores may be higher than market analysts expect. It should be noted that some reviewers mobile market believe such shipments are likely to reach 150 million to 200 million units, or more than a dozen percent of global 5G phone shipments next year.

After a lot of rumors in the news of the cryptocurrency market. On Tuesday, Facebook's plans for next year were revealed, including an ambitious release of a new digital currency called Libra (or Libra). It will be managed by an association made up of corporate investors. Payment companies Visa, Mercado Pago, PayPal, Mastercard and Stripe become partners. Technology companies Uber, eBay, Spotify and Lyft are joining the project. European telecommunications companies Vodafone and Iliad are also participating in the new project. Investors Union Square Ventures and Andreessen Horowitz, plus academic, non-profit institutions Womens World Banking and Kiva.

Facebook has unveiled a new project called Calibra, a digital wallet for storing and sending Libra "crypto coins".

Billions of people are expected to be able to make payments through their mobile apps using cryptocurrency from the social media giant Facebook. The social network Facebook plans to officially launch a new Libra cryptocurrency project in 2020. Libra is a new type of digital money that is intended for billions of people using mobile applications and social network.

The popular social Facebook networks there is more news for the cryptocurrency world.

To create a new digital wallet that will allow users of the Facebook app to store and exchange cryptocurrency. Facebook creates a new subsidiary, Calibra.

Why is Facebook betting on a cryptocurrency called Libra? Perhaps the high goal of the latest development, to go beyond social networks.

Digital wallets for storing, sending and spending Libra cryptocurrency will be connected to messaging platforms.

Initially, the cryptocurrency will be available in the Facebook Messenger / WhatsApp application, and of course in separate applications for iOS or Android.

Facebook said in a press release that: "Initially, Calibra will allow easy and instant sending at Libra's low cost to virtually anyone with a smartphone."

It also states that: "Over time, additional services will be offered for businesses and individuals. For example, buying a cup of coffee with a code scan, paying a bill at the touch of a public transport without having to take cash with you.

Facebook cryptocurrency wallet security.

To improve the security of the new cryptocurrency, it will use similar verification and anti-fraud features that are already used by credit cards, banks. Cryptocurrency service Facebook will have user support. And in case of access to account the user of someone else is promised compensation for lost assets.

Cryptocurrency coins will be stored by users in a digital wallet. But, the world of cryptocurrency itself is not always stable! Time will tell if Facebook's own digital money helps people save money by sending and spending it with the ease of sending text messages.

The cryptocurrency will be managed by the founding members: Facebook, more than two dozen different organizations and a separate Swiss foundation.

Why Libra?

What does the word Libra mean?

Former PayPal CEO David Marcus, head of the Facebook project, said something like this: "The choice of the name Libra (Libra) was inspired by several reasons, namely the French word Liberty, the Roman measurement of weight, the astrological sign of justice."

Technology & Design News: Insanely beautiful iPhone 11 concept with innovative, color, curved screen.

Tech giant Apple will release the iPhone 11 this coming September. If all sorts of rumors turn out to be true, then the multimedia phone could have the same design as the last two generations of the phone. Regarding the final design of the iPhone 11, we are ready to accept what the designers from Apple will offer. But, we can't stop imagining what it would be like if technology made it possible to create any iPhone design 11. And that's exactly what very talented designers do. This time around, a beautiful iPhone 11 concept has been created that ditches all buttons in favor of an immersive, curved phone screen.

The implementation of this design results in an iPhone with a beautiful luminous strip that stretches along the entire mobile phone and replaces the physical volume rocker buttons and the power button. Using this philosophy in design results in an iPhone with on-screen icons on the side.

While it may be a nice looking phone, there is absolutely no chance that the concept will become a reality. In addition, protecting such a phone with a case seems impossible, since by covering the screen space, the case will take away some of its main functions. Imagine if such a phone were accidentally dropped to the ground, the cost of repairing a curved screen would be higher for the user than with a classic screen.

We hope that new iPhone 11 will have a bright screen under the sun.

The 2019 iPhone 11 lineup is expected to feature three models, just like last year. There will probably be two OLED phones and one with an LCD screen. The iPhone 11 and 11 Max models may have a variety of OLED screens, as well as screen sizes of 5.8 and 6.5 inches, respectively. It is possible that the iPhone 11R model will be equipped with an LCD display to keep the price to a minimum.

It is also expected that new iPhone versions The 11 and 11 Max will have a triple camera configuration, while the iPhone 11R version is expected to feature a dual camera setup. In essence, this means that all three mobile phones may receive additional camera behind.

The front of the iPhone 11 lineup is expected to remain the same and there will be no difference in notch size. However, recent reports claim that there may be improved face identification that can authenticate a user from some sharp angles.

Video review of the iPhone 11 concept with an innovative, curved screen on the side:

According to the creator of this video, the new frameless iPhone 11 could have the specifications:

6.4" full screen display;
- Hidden front 13MP camera;
- Four cameras, 8K @ 120 FPS;
- New operating system Apple, iOS 13;
- Apple A13 Bionic mobile chip (up to eight times faster than A12 Bionic chip).

WWDC is Apple's global developer event. During this event, Apple tells developers and interested visitors about new versions of the MacOS and iOS operating systems, its latest development tools, the latest native applications, devices. She talks about plans to stimulate further development, about new partnerships with developers and other details that she is working on. It so happens that attending the Apple WWDC 2019 IT conference is an ideal chance to be the first to find out and see what new applications will be for iOS and MacOS systems and not only.

The telephony has embraced everyone. Very often you can meet 7-8-year-old kids who are calling their friends with might and main.

Why do you still need a cell phone and who needs it more: parents or children?

A mobile phone is a means by which parents control their children, and thereby delay their growing up. “Children need to be in control,” many parents think, and buy mobile phones for their kids in an attempt to assuage their own fears.

Daniela Brancati, a child psychologist, says: “Parents fear every moment their child spends outside the home, they believe that their child may be in mortal danger, especially at school.”

Why does a child need a cell (mobile) phone?

Children need a cell phone to feel grown-up, independent and free. This increases their rating in the eyes of friends and peers, opening up access to the desired communication, videos and games. Children believe that with the help of a mobile they win their independence. Doubt remains: under control cell phones children do not become adults.

The real need to buy a cell phone for a child is a busy schedule of various extracurricular activities, when it is difficult to coordinate actions.

Warn the child that it is better to carry it in your pocket or briefcase, not showing it unnecessarily to strangers and on the street.

Is a cell (mobile) phone harmful?

Scientists have not yet reached a final opinion on this issue. It has been proven that a mobile phone (as well as other electrical appliances) emits waves that, with prolonged exposure to the brain, can worsen well-being. However, the phone can seriously harm your child and lead to hearing problems if the volume is not adjusted.

Having made a positive decision to buy a phone, you should understand that spending is just beginning. Children do not always understand what is paid and what is not. good way out- ban paid services. You can arrange it at the office of your company mobile operator. This will save your budget from various expenses on paid SMS services, mobile games and applications.

Each parent must decide whether his child needs a mobile phone or whether this invention can still be dispensed with.

Today, the role of a mobile phone in a person's life is difficult to overestimate. With the help of this compact device, we can quickly contact our relatives and friends, work colleagues at any time to find out the information we are interested in. At the same time, there is no need to strain your memory and remember the phone of an old friend who has not been dialed for a long time, a mobile phone notebook is always at hand. Many, in addition to contacts, store a lot of other information on the phone - write down their ideas and thoughts, credit card numbers, memorable dates, various files etc. That is, the phone immediately replaces our address book and flash drive. And all kinds useful programs, the features that modern cell phones are equipped with options make this small device so multifunctional that sometimes you wonder.

Today, a telephone in our lives is not a rarity or a luxury, although some fifteen years ago it was hard to imagine that even small children would walk around with a tube in their pocket. And if at that time someone brave decided to dream up and imagine that phones would have in the near future - touch screen, camera, video camera, radio, TV, Internet, navigator, flashlight… such a person would be looked at as crazy.

Mobile phone in human life is indispensable assistant, it benefits those who value their time and are not ready to waste it. Imagine how much time we would spend looking for things that we suddenly needed if this wonderful contraption did not lie in our pocket. Take at least car repairs and the search for some rare spare parts. Without a phone in our lives, we would have to travel to a bunch of stores and spend a lot of time. And then he called, found out (I found where it is cheaper), went and bought it. The benefits of a mobile phone are obvious - saving time and money.

For a business person, the use of a cell phone is the ability to negotiate, reach an agreement with partners at any time and in any place. It's hard to imagine how much it would fall work productivity if businessmen and entrepreneurs would not be able to conclude a contract, give an order or resolve any other issues while out of the office.

A mobile phone in the lives of some people is also part of the image. People buy certain models to show their belonging to a class. Of course, it happens exactly the opposite, more than once I noticed a respectable person in a luxury car with an old phone model. But this is rather an exception to the rule.

What is the use of a mobile phone for a person in an emergency situation? Anyone who has found himself in difficult conditions and circumstances (perhaps was on the verge of death) knows what benefits a cell phone has. Often it is mobile phones that save people's lives, protect them from danger and help in difficult life situations.

In recent years, cell phones have become an integral part of our lives. And this is not surprising, because the high rhythm of life, the implementation of everyday goals and tasks dictates the need for us to always be in touch and have a faithful assistant at hand.

It is also impressive at what tremendous pace the development of cell phones is going on, every day more and more new models appear. Therefore, choosing and buying a phone becomes a daunting task.
